Tom -
I think it has to start with the premise that architects *can* be ranked -- not their courses, but their talent. Now, from what I can tell, you have always argued against that, ie against the notion that the designer can be separated from (and judged independently of) the design, or that his understanding of architectural principles can be 'quantified' and his ability & ingenuity in making those principles manifest on the ground can be 'ranked'. On that front, I've always had the temerity (or foolishness) to disagree with you; and, knowing that I myself couldn't do that kind of judging has never led me to conclude that someone else couldn't either. But if we (ie you) can now bring ourselves to accept that premise, we then have -- as Joe H suggests -- another potential 'list', with the value and import and interest of that list wholly dependent on the credibility and bona fides of the person creating it. (I believe that Bobby Orr was the greatest player ever to lace up a pair of skates; it means little coming from me, but a lot more coming from the likes of Don Cherry.) You and Joe and Ian and Mike and Don etc etc can indeed produce such a list, right today if you'd like; and I for one think it would be a very useful (and even important) list -- mostly because it would bring to the fore the very concept of gca's fundamental principles. But again, it all & completely depends on embracing what so many of you in the industry seem so loath to embrace (especially publicly), ie that there are, to put it bluntly, very talented architects and less talented architects and no talent architects and the most talented architects of all time.
In short: I'm convinced that there are those who know which architects past and present are which, but that those who do know simply aren't telling.
